    Modification of surface properties of high and low intensity polyethylene by Ar plasma discharge

  • Original language description

    Structural changes induced by Ar plasma discharge in low and high density polyethylene (LDPE and HDPE) were studied by different techniques. AFM and SEM methods were used to determine surface morphology, the changes in chemical structure were followed using FTIR and UVevis spectroscopy. The content and the depth profile of incorporated oxygen was determined by RBS method. The degree of polymer ablation was determined gravimetrically. Standard goniometry was used to determine contact angle and to followaging of plasma modified polymer. As a result of plasma treatment a lamellar structure or spherulites appear on the surface of HDPE and LDPE, respectively. Pronounced increase of the surface roughness is observed on HDPE contrary to LDPE. Plasma treatment for 400 s leads to the ablation of the surface layer of about 0.6 and 1 mm thick for LDPE and HDPE, respectively. Plasma treatment results in oxidation of the polymer surface layer which is more pronounced in HDPE.

    Modifikace vlastností povrchu polyetylénu s vysokou a nízkou hustotou s využitím argonového plasmatu

  • Czech description

    Strukturní změny indukované plasmatem v polyetylénu s nízkou a vysokou hustotou (LDPE a HDPE) byly studovány metodami AFM a SEM pro určení morfologie upravených polymerních vrstev a změny chemické struktury povrchů byly studovány metodou FTIR a UV -VIS spektroskopie. Hloubkový profil zabudovaného kyslíku byl sledován metodou RBS. Stupeň ablace polymeru během plasmatické úpravy byl determinován pomocí gravimetrie. Standardní goniometrická měření byla využita pro určení stárnutí a modifikace polymeru. Výsledkem byla lamelární a sferulitická struktura na povrchu polymeru. Významné zvýšení drsnosti povrchu bylo zaznamenáno především v případě LDPE.
